Basically this: all their pedals are direct copies of DIY-projects with a really over the top marketing that crosses the border of knowingly lying rather often. Usually the pedals have one or two very badly executed mods that are explained by even more marketing-mumbojumbo or thrown an SHO into...
Hahaha - that pcb-text had me laughing out loud: "Baron von Wilhemshaven" is probably the funniest thing ever to call out jptr for their continuous lying about their circuit 🤣
Would love to see a pcb for this great 80s chorus/flanger/vibrato!
There's a completed project on FSB: https://www.freestompboxes.org/viewtopic.php?f=1&t=18002&start=160
and also a good, readable schematic: Schematic_TCF - TC ELECTRONIC - TCF.pdf
You can practically add one to any of the FV-1 designs by connecting a SPST-switch (momentary or latching to taste) to lug 2 of the feedback/decay pot and one of the many 3V3-sources on the board, effectively ramping the feedback to maximum for the duration of you pressing the switch.
